A two-vehicle car crash along a slushy Lanham-Severn Road in Glenn Dale claimed the life of two and injured two others, but Prince George’s officials said the county is otherwise weathering Monday’s snowfall relatively well and urging residents to use caution on roads.

Around 8 a.m. in the 10000 block of Lanham-Severn Road, a red Honda traveling west struck an oncoming silver Audi in the eastbound lane, Prince George’s police said.

Both drivers suffered non-life-threatening injuries but the two passengers in the Honda died, said Officer First Class Nicole Hubbard, a county police spokeswoman. One passenger died at the scene while the other was taken to a hospital and died a short time later, Hubbard said.

All occupants were trapped in their vehicles when emergency medical personnel arrived and had to be extricated from the vehicles, said Mark Brady, a county fire/EMS spokesman.

Brady said the weather — portions of the county received up to three inches of snowfall — may have played a role in the crash.

“There was still heavy snow [at the time of the accident],” Brady said. “Some parts of the road were snow-covered and others were wet, and those factors may have contributed to the crash.”

Hubbard said the cause of the crash has not been determined.

“Obviously, there’s snow and weather conditions, but it’s too early in the investigation to say 100 percent that snow is a causing factor,” Hubbard said.

The crash occurred near several auto body and mechanic businesses, some of which had shop owners there who were first to witness the wreckage.

“One man was hanging out of a broken window, and it looked like he had expired,” said Nazir Ali, 63, who said he heard the crash and ran to help. “The guy in the silver car was waving out of his window saying, ‘Help, help, help.’ I held his hand just to comfort him a little bit.”

Ron McGraw, who works at Brevard & Son Auto Service, said he heard a loud bang and called 911.

“No one was moving when we got there. ... I just felt helpless because I couldn’t do nothing. I didn’t want to move anybody. It’s just a helpless feeling. The guys were literally hanging out of the car,” McGraw said.

Brady said that the Glenn Dale crash was the only major incident despite what he described as an increased call volume.

“The two-hour delays in schools certainly helped,” Brady said. “Most roadways appear clear now, and even some secondary roads. There are still some slick spots, so everyone should exercise caution on the roads.”
